Throughout its history, Operational Research has evolved to include methods, models and algorithms that have been applied to a wide range of contexts. This encyclopedic article consists of two main sections: methods and applications. The first summar... Read More about Operational Research: Methods and Applications.

When to Switch? Index Policies for Resource Scheduling in Emergency Response (2019)
Journal Article
Li, D., Ding, L., & Connor, S. (2020). When to Switch? Index Policies for Resource Scheduling in Emergency Response. Production and Operations Management, 29(2), 241-262. https://doi.org/10.1111/poms.13105

This paper considers the scheduling of limited resources to a large number of jobs (e.g., medical treatment) with uncertain lifetimes and service times, in the aftermath of a mass casualty incident. Jobs are subject to triage at time zero, and placed... Read More about When to Switch? Index Policies for Resource Scheduling in Emergency Response.

Ownership, Capital Structure and Financing Decision: Evidence from the UK (2015)
Journal Article
Sun, J., Ding, L., Guo, M., & Li, Y. (2016). Ownership, Capital Structure and Financing Decision: Evidence from the UK. The British Accounting Review, 48(4), 448-463. https://doi.org/10.1016/j.bar.2015.04.001

This paper examines whether and to what degree agency conflicts in ownership structure affect firm leverage ratios and external financing decisions, using a universal sample of UK firms from 1998 to 2012. We use two distinctive measures to capture ow... Read More about Ownership, Capital Structure and Financing Decision: Evidence from the UK.

Optimal Currency Composition for China’s Foreign Reserves: a Copula Approach (2014)
Journal Article
Zhang, Z., Ding, L., & Zhang, F. (2015). Optimal Currency Composition for China’s Foreign Reserves: a Copula Approach. World Economy, 38(12), 1947-1965. https://doi.org/10.1111/twec.12237

This paper investigates the optimal currency composition for a country's foreign reserves. In the context of China, we examine the asymmetric, fat-tail and complex dependence structure in distributions of currency returns. A skewed, fat-tailed and pa...

Fund Family Tournament and Performance Consequences: Evidence from the UK Fund Industry (2014)
Journal Article
Zhang, Z., Ding, L., Zhou, S., & Fu, Y. (2014). Fund Family Tournament and Performance Consequences: Evidence from the UK Fund Industry. Multinational finance journal, 18(1/2), 43-84

By applying tournament analysis to the UK Unit Trusts data, the results support significant risk shifting in the family tournament; i.e. interim winning managers tend to increase their level of risk exposure more than losing managers. It also shows t... Read More about Fund Family Tournament and Performance Consequences: Evidence from the UK Fund Industry.

Investor learning and mutual fund family (2013)
Journal Article
Zhang, Z., Ding, L., & Zhou, S. (2014). Investor learning and mutual fund family. Journal of Empirical Finance, 26, 171-188. https://doi.org/10.1016/j.jempfin.2013.12.001

In this paper we revisit the cross-fund learning method suggested by Jones and Shanken (2005) and construct a linear hierarchical model to consider the learning across funds within the fund family during the performance evaluation. We provide a full... Read More about Investor learning and mutual fund family.

Dynamic routing of customers with general delay costs in a multiserver queuing system (2009)
Journal Article
Argon, N., Ding, L., Glazebrook, K., & Ziya, S. (2009). Dynamic routing of customers with general delay costs in a multiserver queuing system. Probability in the Engineering and Informational Sciences, 23(2), 175-203. https://doi.org/10.1017/s0269964809000138

We consider a network of parallel service stations each modeled as a single-server queue. Each station serves its own dedicated customers as well as generic customers who are routed from a central controller. We suppose that the cost incurred by a cu...

Allocation Models and Heuristics for the Outsourcing of Repairs for a Dynamic Warranty Population (2008)
Journal Article
Ding, L., Glazebrook, K., & Kirkbride, C. (2008). Allocation Models and Heuristics for the Outsourcing of Repairs for a Dynamic Warranty Population. Management Science, 54(3), 594-607. https://doi.org/10.1287/mnsc.1070.0750

We consider a scenario in which a large equipment manufacturer wishes to outsource the work involved in repairing purchased goods while under warranty. Several external service vendors are available for this work. We develop models and analyses to su...

A static allocation model for the outsourcing of warranty repairs (2005)
Journal Article
Ding, L., & Glazebrook, K. (2005). A static allocation model for the outsourcing of warranty repairs. Journal of the Operational Research Society, 56(7), 825-835. https://doi.org/10.1057/palgrave.jors.2601904

There has been a strong recent trend among original equipment manufacturers toward the outsourcing of work relating to the repair of items under warranty. In the typical cases where a large manufacturer uses several vendors to perform such work, we d... Read More about A static allocation model for the outsourcing of warranty repairs.
